* Config - add error checking into config_streamer.c, CONFIG_STREAMER_BUFFER_SIZE does not match actually writen data in some cases * Config - fix buffer read ovefrflow CONFIG_IN_RAM and CONFIG_IN_SDCARD used 4 byte byffer, but 32 bytes got actually copied CONFIG_IN_MEMORY_MAPPED_FLASH used 8byte buffer, but but 32 bytes got actually copied * Config - add write functions into header --------- Co-authored-by: Petr Ledvina <ledvinap@hp124.ekotip.cz>
